Crankcase mounting bolts: Upper Case 10Nm, Lower Case 25Nm
25nm then 3 x 60 degrees
intake nut 89lb .in stud 106.lb.in plenum is 25nm
Is this for trivia or are you too lazy to look? OK... Its on the drivers side of the drain pan, and the torqe is 25Nm.
corsa 1,3ie,nv or sv motor,head settings 25nm @ 60deg + 60 deg + 60 deg
Head nuts 18 ft-lb (25Nm), cylinder base nuts 25 ft-lb(34Nm)
25nm on all 4 bolts 1, 2 , 3 , 4 then 90 degrees and 90 degrees
A nanometre is 1x10^-9 metres and a millimetre is 1x10^-3 metres. Therefore there are 1x10^6 nanometres in a millimetre or 1,000,000. 25nm/1,000,000 gives 0.000025mm
Astra F stage 1. 25Nm stage 2. + 60 degrees Stage 3. + 60 degrees Stage 4. + 60 degrees.
Using new head bolts & lubing the threads tighten to 25Nm then a further 90 degrees+ another 90+ another 90+ 45 degrees.
Mains stage 1. 35Nm stage 2. 70Nm Big Ends stage 1. 25Nm stage 2. 50Nm.
New head bolts must be used Stage1. 25Nm Stage2. +90 degrees Stage3. +90 degrees Stage4. +90 degrees.
